To orari corr. rrniirnn s'rnaivr PACKING .Torun Application filed September 2U, 1920.- Serial No.-411,655.

To all whom it may concern: i i 1 Beit known that l, Conn- SrroxLn, a citi- Yen of the United. States, andaresident of` indianapolis, county of Marion, and State of indiana, have invented acertainnew and useful Steam Packing Joint; and li do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like numerals refer to. like parts.

This invention relates to improvements in packing boxes adaptable for use with steam heated drying cylinders for textile machines.

The particular feature of the invention relates to the means for securing and supporting the siphon and vacuum valve independently of each other, and in direct communication by the nut 26 which acts as a head member mounted upon the cylinder bearing for closing the end thereof. This arrangement permits of the ready removal of the siphon, head member or valve, and the position of the Siphon will not be affected by the position of the valve.

Another feature of the invention lies in the manner of mounting the siphon and valve in the head member, whereby each of them screw therein so that their ends abut,

direct communication and providing a steam-tight fitting so as to prevent any leakage of steam through the end of the bearing between the head member and the Siphon.

`'llhe full nature of this invention will be understood from'm the accompanyingdrawings and the following description and claims.

ln the drawings F ig. 1 is a central vertical cross section taken longitudinally of a portion of the drying cylinder, bearing and packing box showing the vacuum valve in elevation. F ig. 2 is a central longitudinal cross section through the bearingand packing box showing an enlarged view thereof. Fig. 3 `is a section taken on the L1 is a section taken on the line @-11 of 2.

In the drawings there is shown a drying cylinder or can of the usual construction employed for drying textile and the like,

a head 11 at each end said cylinder having thereof, the head 11 being provided with a `hollow journal 12 for supporting the head and cylinder in the bearing 13. The bearing 13 is supported upon the upright supports 14 of the base 15 ofthe machine. v Livev steam is supplied j to the4 cylinder 10 through' the` conduit 16 extending upwardly through the upright 14 and discharging into the bearing 1.3,.and.- thence through the` hollow journal 12l into 4the inside of the cylinder for the purpose of heating the surface thereof and drying the textile.

In order that the water accumulating within `the cylinder from the condensation of the steam may be removed, a Siphon pipe 17 is provided having its open end in close proximity to the lower inner surface of the cylinder, and extending out through .the head 11 and hollow journal 12 where it is operatively connected with the vacuum valve 18 which, by reason of its construction not shown herein, will cause the water to be siphoned, or sucked from the cylinder 10.

As it has heretofore been diiiicult to prevent the live steam, entering throughthe bearing and spindle, from escaping between their surfaces, a packinglbox is provided in the outer end of the bearing 13 whereby a tight seal may be obtained and maintained by the proper adjustment thereof. The outer end of the bearing is enlarged to make room for the packing and is provided with internal screw threads adjacent its outer end. The packing material 19 is placed between the bearing and journal in the enlarged portion of the former and is held therein by the packing ring and follower 20 that likewise ts between said journal and bearing and is provided with a beveled end 21 which is oppositely beveled from the an gular surfaced shoulder 22 of the bearing. Because of the oppositely beveled surfaces of the ring and shoulder of the enlarged portion of the bearing, between which the pack ing material is placed, the packing material is caused to be forced inwardly against the bearing surface of the spindle by the inward pressure exerted on the ring 20, The pressure is applied to the ring follower 20 by means of the bolts 25 which `screw through the nut 26. Said nut is provided with an annular engage the end of the screw threads which press against the side of the ring 20 and cause it to squeeze the packing inwardly against the bearing Surface of the spindle by the packing, the pressure may be released by unscrewing the bolt 25 just enough to release the spindle and Still prevent the escape of steam.

The invention claimed is:

1. In combination, a drying can for textile machines having a journal, a bearing for said journal through Which Steam may enter Said can, and a vacuum valve, of a Siphon adapted to extend through Said journal, and a head member mounted on Said bearing for Supporting said vacuum valve and one end of said Siphon independently fixed my signature.
